Lovely soft light, great background colors, nice angle of the bird, and composition. I like the attention he is paying to the bubble. From a composition standpoint, I wonder about cloning out the other bubbles, just leaving the one he is looking at?
The image seems a bit noisy to me, in the blacks on the bird and darker areas of the background.
I love this as presented. Stunning light and a wonderful low angle and excellent exposure. Avocets are so beautiful but to see them in this lighting just puts it over the top for me. The bubbles add another element of interest to this composition. Love it Fab and I wish I had been there :(:(
